TURBINE-ENGINE. l

Specification of Letters Patent.

Patented Jan. 1c, 1906.

To all whomfit may concern: Be it known that I, GAsToN CHARLES EMILE DE BONNECHOSE, a citizen of the French Republic, residing in Paris, France, have'invented certain new and useful Imrovements in Turbine-Engines, of which the ollowing is a specification.

This invention relates to rotary engines or pressure, and has for its object to provide me compressorand which may be operated as steam, com ressed air, products of combustion, and e like. In this engine or device are utilized the successive reciprocal thrust or reactions between an elastic fluid under pressure emitted 'from fixed adjuta es and buckets or; similar devices on a rotata le wheel, the buckets or its equivalent having a conduit or passage for the fluid which is contracted at one or more points in its length.

iving an undulatory contour to one or of the lateral walls of the conduit or assage, as will be hereinafter explained. T s conduit may be as a whole annular and concentric with the axis of the carrying-wheel, or it disposed symmetrica ly about said axis and having a uniform obliquity to the radius of the Wheel.

In the accompanying drawings, which illustrate several forms of the engine, Figure l is a diagrammatic view showing a bucket having the passage therein provided with a single contraction formed by the undulating lateral walls of the bucket. Fig, 2 is a'sectional view of a part of the crown or peripheral portion of the wheel or rotary .part'of an axial turbine developed, the plane of the section along line X Y in Fi 4. Fig. 3 is a crossiTxed adjutages A. Fig. 4 is a section through a bucket B at line XY in Fig. 2. i In the construction seen in Fig. 2 the buckets Main series separated by partitions. Fi 5 is a section similar to Fig. 2 developed, s lowing the bucketering of annular form and' without partitions. Fig. 6 is a section at Z Z in Fig. 5, and Fig. 7 is a section at X Y in Fig. 5. 8 is a sectional view illusthrough the casing of the engine.

trating another way of forming the contractrons 1n the conduits of they buckets or bucket-ring of the turbine. Figs. 9, 10, and

11 are sectional views illustrating another way of producing pansions in the bucket-conduit by undulations in its walls. Fig. 9 is a diagrammatic elevation showing the parts developed and the adjutages in section. Fig. 10 is a transverse section at X X in Fig. 11, and Fig. 11 is a section at line Y Y in Fig. 10. Figs. 12 and .13 illustrate the invention as'applied to a centrifugal turbine-engine, the'former being a vertical axial section in plane of the shaft and the latter a section at right angles thereto In Figs. 1, 2, 5, 8, 9, and 10, A the fixed adjutagesthrough which the compressed fluid flows' to the buckets-of the turbine or rotary part, and in Figs. 1, 2, 4, 5, 6, 7, 10, and 11 B designates the undulating Walls of the passage or conduit in the bucket the contractions and exdesignates or bucket-ring of the rotary part. This pas- 7 5 sage orconduit is capable of being formed or produced in many ways, as will be hereinafter described. The forms shown in Figs, 1 to 7 will be first described.

Fig. 1 shows a bucket formed of two undu-' latinglateral walls producing a single contraction of the passage through it. The fluid enters it at the outer end from the adjutage A. The axis of the curvature of the Wall at the contracted part will be perpendicular to the direction of the flow of the fluid, or nearly so. In Figs. 2and4 the bucket is shown as' having two contractions in the length of the conduit or passage through it, and the buckets are separated by partitions equally spaced and terminating at their inner ends in curved blades F. At their outer ends the buckets abut against a wheel-rim apertured or ported at E to admit the fluid fromthe adj utages to the respective buckets of the series. In

Figs. 2 and 5 the curve of the parts is developed into a straight line for convenience of illustration In the species illustrated in Figs. 5, 6, and 7 the construction is substantially the same as that of Fig. 2, except that the partitions between the buckets of theseries are omitted, and the lateral walls-of the bucket devicev form an annulus or ring provided with suitably-spaced" curved blades F. In this construction also the contracted arts of the conduit through which the flui flows'are more numerous, five being seen in Fig. 7, and the degree of contraction becomes gradually less and less from E to F.

The construction shown in Fig. 8, which is a transverse section, illustrates how three conduits with contractions may be formed in the bucket-ring of the rotary part. In this construction the wheel-rim or bucket-ring has a central passage or conduit formed of two parts D, the inner and outer lateral faces of which have undulating contours and twoouter passages or conduits, the exterior walls of which are formed of fixed ring-plates C. These latter form a flared casin connected with the adjutages A. Thus t e contractions in the outer conduits are formed wholly by the undulating surfaces of the part 1).

In the construction illustrated in Figs. 9, l0, and 1.1 the rim of the turbine-wheel, the rotary part, has undulating lateral outer faces, and the fixed casing C has also undulating inner faces. The rounded ribs forming t e undulating inner faces of-the casing G, however, extend substantially parallel with the axes of the adjutages A,'while those on the rotary part extend substantially at right angles to those on the fixed part Thus the undulating inner surfaces of the casing serv somewhat as extensions of the adjuta e A. g

igs. 12 and 13 illustrate a construction wherein the flow of thefluid is outward ra-' dially through a bucket-rim on the rotary part, having conduits rovided with contractions similar to those escribed. In this construction, which is that of a fluid motor, the fluid enters a chamber H in a casing I J through an inletG and flows throug ad- 'utages between fixed directors K to the ucket-ring- Q of the wheel M, carried by a shaft or arbor having hearings at O and P.

The directors K are fixed in the casing bybolts L, and the bucket-rim Q is secured to the wheel M by arms N. The fluid impinging uponand passin through the'bucket rimz in such a manner as to present a series of un- The bucket-rim in Fi s'. 12 and 13 is herein shown as composed 0 threerings placed; abreast and having undulating lateral sur- Qfinally escapes at t e exhaust R.
